Tenant database replication

A computer-implemented system for replicating a tenant database from a source system to a target system, the system comprising:

• one or more data processors;
• and
• a computer-readable storage medium encoded with instructions for commanding the one or more data processors to perform operations comprising:
• receiving, at a source system, a first request from a target system for replicating a first tenant database of the source system, the first tenant database including one or more first servers;
• sending to the target system characteristics of the one or more first servers included in the first tenant database to generate at the target system a second tenant database including one or more second servers, each second server corresponding to one first server and having the same characteristics as the corresponding first server;
• establishing a communication channel between each first server and the corresponding second server;
• replicating, in an asynchronous mode, information from each first server to the corresponding second server through the communication channel;
• in response to receiving a second request for stopping replication of the first tenant database to the second tenant database, entering a synchronous mode of processing statements from client applications of the first tenant database.

A computer program product for replicating a tenant database from a source system to a target system, the product comprising:

• a non-transitory machine-readable medium storing instructions that, when executed by at least one data processor, cause the at least one data processor to perform operations comprising:
• receiving, at a source system, a first request from a target system for replicating a first tenant database of the source system, the first tenant database including one or more first servers;
• sending to the target system characteristics of the one or more first servers included in the first tenant database to generate at the target system a second tenant database including one or more second servers, each second server corresponding to one first server and having the same characteristics as the corresponding first server;
• establishing a communication channel between each first server and the corresponding second server;
• replicating, in an asynchronous mode, information from each first server to the corresponding second server through the communication channel;
• in response to receiving a second request for stopping replication of the first tenant database to the second tenant database, entering a synchronous mode of processing statements from client applications of the first tenant database.
